THIS IS A BIKEPACKING-FLAVOURED offshoot of the US brand's venerable gravel bike range. It features a 1x drivetrain, dropper post and even comes with a frame bag. It sits below the carbon Checkpoint SL and SLR so that means no down-tube storage or compliance-boosting IsoSpeed. Neither do you get cable integration, but this does make maintenance easier.

It's made from Trek's lightest 300 Series Alpha Aluminium, producing a 1,490g painted frame weight (claimed) in a size 56cm, and 580g fork. Seatstays aren't dropped and the thin, round seat tube is fairly traditional. But there's a dropped driveside chainstay so you can fit 700x45mm gravel bike tyres. The carbon fibre fork is like the Checkpoint SL's.
